Even 3-4 years ago, the cable operator knew for sure that the best solution for providing a triple play service package (television, Internet access and telephony) was a cable television network with a reverse channel for data transmission using DOCSIS technology. This concept of cable networks was supported by all CATV equipment manufacturers without exception, providing the ability to equip all active distribution equipment passive or active backchannel modules. Exactly following this concept, a huge number of large and small cable networks were built in Russia. Not all constructed networks have actually used the reverse channel, but almost any cable operator using the equipment of such vendors as Teleste, Wisi, Hirschmann, Arcadan, Fuba, C-Cor, Gl, Vector and many others has the potential to activate the reverse channel. .

In Russia, there are examples of quite successful commercial triple play projects implemented using this technology, for example, in Kostroma, many thousands of subscribers of the cable network of the Verkhnevolzhsky branch of CenterTelecom receive not only multi-program cable TV and the Internet, but also the service telephone communication using cable modems, with telephone adapters. It would seem that having introduced a triple play service package (or, more often, double play, i.e. without telephony) at the base at one time advanced technology DOCSIS 2.0, the cable operator could feel quite confident in the market for more than one year. However, in the last 3-4 years, the market situation has been rapidly changing, and in the new conditions, the cable operator, which has a classic HFC network with a reverse channel, is clearly losing its positions to operators with a higher technological level.

AT recent times already not only in Moscow and other large cities of Russia, but also in small regional and district centers, competition in the market for broadband access services has become extremely aggravated. If a few years ago it was enough for operators to “capture” the most attractive territories in a timely manner and geographically divide the zones of influence, now it is already quite common practice that several multiservice operators operate in the same territory at once. Furthermore, large companies start expansion or buy up regional players, hoping to cover the market faster.

Let us briefly list the most important trends in Russian market broadband access services that are already in place or expected in the very near future:

• tougher competition even in small settlements;
• entry into the regional markets of large all-Russian players;
• mass enlargement (unification, absorption) of operators;
• a significant increase in access speeds and quality of services;
• emergence of new services (HDTV, VOD, content on demand, etc.);
• emergence of new business models, penetration of products and services of non-mass (targeted) demand into the television advertising market, etc.

Naturally, in the face of such intense competition, operators providing subscribers and corporate customers with the most advanced level of broadband access have the best prospects. In connection with the increased modern market requirements, the widespread construction of MetroEthernet networks begins, providing the subscriber with an unprecedented access speed of 100 Mbps, and large corporate customers can connect directly to the IP backbone, in which speeds range from 1 to 10 Gbps. Such high access speeds make it possible to provide a variety of previously inaccessible services, for example, IPTV in the format high resolution for several TVs in the apartment at once, network ultra-dynamic games and much more.

It is clear that a multiservice operator building its network “from scratch” today has good reasons to build a network using the “Optics to the Home” technology with a parallel GigabitEthernet network physically connected in a common building infrastructure with a television network, in other words, for each logical network is allocated its fiber in the backbone optical cable. But what is the current situation of a cable operator that has long built its broadband network on the basis of far from obsolete technologies with a developed infrastructure and a reverse channel and has invested a lot of money in its construction? Can it provide subscribers with an access speed commensurate with the offers of MetroEthernet operators? Can it provide the latest ultra-advanced services based on the ultimate high speed access?

Having honestly answered these questions, we must state that today, in the conditions of such intense competition and the emergence of the latest advanced access services, a cable operator that has a technological base for data transmission based on latest version DOCSIS, i.e. DOCSIS 2.0 can no longer fully meet modern market requirements. Using the DOCSIS technology of version 2.0 or later, deployed by most operators, it is impossible to achieve a data transfer rate of more than 55 Mbps for sufficient large group subscribers, but in reality per user - no more than 25 Mbps.

The cable operator is beginning to feel acutely that DOCSIS 2.0 technology puts limits on the development of value-added services, namely high-speed and ultra-high-speed Internet access, IP-telephony, etc. In the conditions of fierce competition with MetroEthernet operators, the cable operator is experiencing more and more difficulties, having as the main argument for the fight for the subscriber no longer access speed, but more affordable rates, i.e. in any case reduces their income. In addition, the HFC network requires significant staff effort to get it up and running in most cases. Thus, the cable operator, on the one hand, continues to incur significant operating costs, and on the other hand, cannot make an adequate competitive offer.

In this situation, he actually has 2 ways:

1) either search all existing opportunities to significantly increase the speed of access without changing the architecture and infrastructure of the network, that is, to maximize the considerable, as we will see later, the reserves of DOCSIS technology;

2) either become an Ethernet operator, i.e. build a parallel Ethernet network and operate 2 networks at once, producing significant capital investments and increasing operating costs, which drastically reduces today's profits and pushes the payback period into the future.

Generally speaking, it is quite logical for a CATV operator to use exactly the technology that was invented by the community of large cable operators and manufacturers of telecommunications equipment, namely the DOCSIS standard. The authors, to be honest, have never heard that, for example, COMCAST would seriously consider switching to MetroEthernet, as, however, no one has heard that any major Ethernet provider has seriously ousted even a medium-sized cable or telephone operator in North America. Those. in the US or, say, in Germany, the use of a cable operator other than DOCSIS technology, namely MetroEthernet, PON, etc., is considered unnatural. A natural approach is when the cable lies and is used as long as a broadband signal can be quite successfully transmitted over it.

Also, in recent years, operators are increasingly switching to digital television broadcasting, while using complexes for the provision of services that do not interact with each other in any way, except that they are located within the same rack and use the same network. The generalized solution scheme used by the operators in this case is shown in fig. one.

Fig.1

So how far can a cable operator push the technological limits of DOCSIS 2.0? The answer lies on the surface - not so long ago, thanks to the efforts of the CableLabs consortium, the newest standard appeared - DOCSIS 3.0 with its European version of EuroDOCSIS 3.0, which, apparently, solves all pressing issues and, as usual, does not require the construction of a new network. Moreover, all subscriber devices already installed at subscribers can continue to be used with new DOCSIS 3.0 stations, although they will work with them according to their previous version.

The main advantage of DOCSIS 3.0 is the ability to combine multiple frequency channels, providing much higher access speeds. Explaining how the new standard works, they usually give a graphic illustration showing that when several frequency channels are combined, a kind of “pipe” of a much larger diameter is formed than the “pipe” of a single channel. So, combining 4 frequency channels into a pipe in the downstream allows you to achieve speeds of over 200 Mbit / s.

So, the most important differences between the 3rd version of DOCSIS and the 2nd one are in the combination of channels (channel bonding) downstream and in the combination of channels upstream. Downstream link aggregation is the most important feature of DOCSIS 3.0 and is already supported by a number of cable modem manufacturers today. Already today it is possible to purchase custom modems that support combining, for example, 3 downstream channels, i.e. already today it is possible to give a subscriber a speed of up to 150 Mbps, see fig. 2. And this is already something. This is exactly what knocks the trumps out of the hands of the competitors of the cable operator! In addition, DOCSIS 3.0 provides:

• advanced multicast functions;
• IPv6 support;
• support for improved AES encryption method;
• additional functions management.

See Table 1 for access speed capabilities of each DOCSIS version. one.

CableLabs has also made innovative changes to the CMTS architecture. Now in the new QAM standard, the modulation is physically separated from the DOCSIS MAC. The CMTS still sits between the IP backbone and telematic services on the one hand, and the user modems on the other; the difference is that the downstream modulation block is physically separate. This concept is called M-CMTS (modular cable modem termination system), see fig. 3, and this gives a lot of advantages.

Table #1

Version Speeddownstream, Mbps Speedupstream, Mbps DOCSIS 1.0 (EuroDOCSIS 1.0) 38(55) 2,5(2,5) DOCSIS 1.1 (EuroDOCSIS 1.1) 38(55) 10(10) DOCSIS 2.0 (EuroDOCSIS 2.0) 38(55) 30(30) DOCSIS 3.0 (EuroDOCSIS 3.0) 160 and more (220 and more) 120 or more (120 or more)

First, it effectively reduces the cost of downstream modulation. Secondly, finally, it is possible to combine digital broadcasting with IP through one QAM. Moreover, manufacturers have a free hand to implement DVB-processing options on one platform.

AT this moment many vendors have announced that they support the new standard, but so far none of them have implemented all the features of DOCSIS 3.0, so all implementations are called “preDOCSIS 3.0”. However, the most main task- providing in comparison with DOCSIS 2.0 many times higher speed of incoming subscriber traffic (from 100 Mbit/s) - CMTS stations in preDOCSIS 3.0 version are successfully solved. Further upgrade to full version 3.0 will be produced programmatically. In the opinion of the authors, two vendors from the USA have the most impressive results in terms of the practical implementation of DOCSIS 3.0 systems: BigBand Networks and CASA Systems.

The first vendor, Bigband Networks, unlike all other vendors, provides support for the new standard based on its Cuda 12000 developed for DOCSIS 2.0. Thanks to the innovative MeshFlow architecture, which ensures that all traffic is processed not in the core, but distributed across station modules, which non-blocking and increased reliability and availability of the entire system, the new features of DOCSIS 3.0 are conceptually easily combined with Cuda 12000 and thus make it possible to simply upgrade the software to DOCSIS 3.0, all available interface modules can be used in M-CMTS and beyond. Those who have already purchased Cuda 12000 and installed them are especially lucky. For these operators, migrating to DOCSIS 3.0 will be the easiest and most cost effective. This is very difficult on equipment from other vendors.

The second vendor is CASA Systems, which provides extremely high downstream and upstream density in a single unit device. In particular, a configuration such as 32 ds × 16 us is supported. This high density is achieved thanks to the applied innovative solutions and high engineering skills of developers. In fact, on this moment, is the only pizza box maker for DOCSIS 3.0. This platform is favorably distinguished by the fact that it is used both under DOCSIS, and under DVB, and under IPTV. This is such a universal solution that it is difficult to find an analogue for it. Most likely, it will be a whole rack with various telecommunications equipment, as well as a lot of software solutions. This solution is really unique in that operators choosing the path of building MetroEthernet networks can use such a device later, after a full transition to Ethernet, as a scrambler and QAM modulator for broadcasting in DVB. It should be noted that, unlike many others, these two manufacturers are not limited to declarations of readiness for the release of DOCSIS 3.0 CMTS in some happy future, but are actually placing orders for the production of such CMTS.

For example, BigBand Networks is currently supplying and installing a modular M-CMTS headend to a large cable operator Multikabel (Netherlands), which is the first company in the world to practically deploy a data transmission network based on DOCSIS 3.0. At the same time, CASA Systems offers a ready-to-ship, flexible and efficient solution to the market that provides DOCSIS functionality, as well as QAM modulation in conjunction with PSI / SI processing, CAS Symulcrypt support, etc. on one compact 1U platform!!! Thanks to this solution, the operator can purchase one platform for both tasks, as well as flexibly adjust the bandwidth for services as needed.

Now the implementation of IPTV through this platform, incl. and through DOCSIS, absolutely real. This is the case, for example, for a service such as video-on-demand, which can be allocated a bandwidth in QAM. The deployment of the M-CMTS platform enables more efficient use of UEQ (universal edge QAM). To take advantage of the new DOCSIS 3.0 benefits, you must purchase a new modem. Not every user will want to pay for it. The easiest way to do this is for small businesses, for which the price of the issue is small compared to new opportunities, while most subscribers will weigh and think for a long time. However, this technology allows cable operators to move with the times and more effectively fend off competitive pressure. For example, M-CMTS manufactured by BigBand Networks and CMTS C2200 made by CASA Systems allow cable operators to offer access speeds in excess of 100 Mbps on a single chassis to subscribers with DOCSIS 3.0 modems and speeds of about 25 Mbps to those with current generation modems.

Deployment of the M-CMTS architecture, as the initial stage of the DOCSIS 3.0 move strategy, allows cable operators to grow as the market needs - to add capacity and functionality as demand exists.

Thus, the new standard gives cable operators the opportunity to develop the DOCSIS standard, offer high-speed access over 100 Mbps based on it already now, successfully competing in the access services market, offer a range of services that require a wide bandwidth, incl. DVB and IPTV on the same platform using the flexible M-CMTS architecture. Purchasing solutions based on preDOCSIS 3.0 now, in the future, without replacing the hardware, the operator can switch to the finished DOCSIS 3.0 standard, only by changing software. This allows you to effectively protect the investment made in the construction of the HFC network.

In our opinion, only with the advent of the third version of DOCSIS, this technology made a really strong leap forward, ensuring the introduction of new high-speed services, previous versions only tried to adapt cable TV networks for Internet access, using its resources by 5 percent in the same way as a person uses a tiny fraction of the capabilities of his brain. DOCSIS 3.0 allows you to use the cable TV network at full capacity.

The DOCSIS standard often used by Rostelecom is a technology that allows you to transfer Internet connection data over TV cable. This method of communication with the provider has many advantages, the main of which is the speed and quality of the connection.

What is DOCSIS from Rostelecom?

The solution for data transmission over a television cable was found back in the late 90s, after the approval of the ITU (International Telecommunication Union) of the new J. 112 standard. It became the DOCSIS technology, the abbreviation of which stands for Data Over Cable Service Interface Specification.

DOCSIS technology from Rostelecom in most cases has maximum speed incoming packets 42 Mbps. Outgoing data is sent a little slower. This figure is about 10 Mbps. Such speed characteristics are intended to replace the old standards and open up fast Internet access for numerous customers who use television services.

It is worth noting that DOCSIS communication technologies differ depending on the unique features of regional TV signal transmission standards. The global TV service markets use:

• NTSC (National Television Standards Committee - US standard);
• PAL (UK and Western Europe standard);
• SECAM (joint development of France and the USSR).

The most common now is the PAL standard, which occupies about 65% of the market compared to competitors.

DOCSIS also has a division according to update versions (1.0, 1.1, 2.0, 3.0). The latest and most productive now is the EuroDOCSIS line. These data transfer formats allow you to work more efficiently with both single-channel and broadband lines, thereby increasing the speed of sending and receiving data. Nevertheless, most modern modems on our market support only the classic version of the standard. Since it is practically not inferior to the older one in terms of speed characteristics, there are no good reasons for a costly transition so far.

Having gone through several stages of evolution, this standard, even in the classic version of DOCSIS, allows you to get a reception speed of more than 340 Mbps.

Technology Benefits

The DOCSIS standard from Rostelecom, in addition to a significant increase in the response speed of the provider's server, is ready to offer support for the IPv6 protocol. It is intended to address the shortage of IPv4 addresses in the near future.

Interesting: An important feature is multicasting support. Thanks to multicast data transfer technology, routers have the ability to set up IP television for several devices.

Internet signal transmission using DOCSIS technology from Rostelecom significantly increased data security. This is due to the use of the AES (Advanced Encryption Standard) encryption algorithm, which supports 128-bit keys.

Scheme of connecting DOCSIS clients in the Rostelecom network

Rostelecom's DOCSIS technology uses the Downstream connection scheme, which can be translated into Russian as "top down".

This simplified format involves the distribution of the Internet by the main device (Cable Modem Termination System) to all network users at the same time. The reverse transmission, i.e. Upstream (sending client data to the server), is performed by a supported modem directly to the server without using intermediate devices.

The telecommunications market in large cities is able to offer a wide range of services and types of their connection. Depending on the user's requirements, you can choose the connection standard, the desired speed and, accordingly, the cost of the service. Nevertheless, in many localities, the most common so far is DSL Internet connected via a telephone line.
